EulerSwap
UnichainRegisteredA custom AMM hook that implements a bespoke liquidity curve backed by Euler Finance lending vaults. In beforeSwap, it computes quotes via its own curve, takes input tokens, deposits them into the LP's Euler vault, withdraws output from the counterpart vault, and settles with the PoolManager — replacing standard pool liquidity with yield-bearing vault positions. beforeAddLiquidity and beforeDonate both revert to prevent standard LP usage.
What it can do
Its code executes inside each trade in pools that use it.
It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
It checks every deposit before it goes in.
It runs when a pool is created, often to lock in that pool’s settings.
It runs when someone donates tokens to the pool’s LPs.
